adrian b64fa0490d Update the TSF and next-TBTT methods to work for the AR5416 and later NICs. 
This is another commit in a series of TDMA support fixes for the 11n NICs.

* Move ath_hal_getnexttbtt() into the HAL; write methods for it.
  This returns a timer value in TSF, rather than TU.

* Move ath_hal_getcca() and ath_hal_setcca() into the HAL too, where they
  likely now belong.

* Create a new HAL capability: HAL_CAP_LONG_RXDESC_TSF.
  The pre-11n NICs write 15 bit TSF snapshots into the RX descriptor;
  the AR5416 and later write 32 bit TSF snapshots into the RX descriptor.
* Use the new capability to choose between 15 and 31 bit TSF adjustment
  functions in ath_extend_tsf().

* Write ar5416GetTsf64() and ar5416SetTsf64() methods.
  ar5416GetTsf64() tries to compensate for TSF changes at the 32 bit boundary.

According to yin, this fixes the TDMA beaconing on 11n chipsets and TDMA
stations can now associate/talk, but there are still issues with traffic
stability which need to be investigated.

The ath_hal_extendtsf() function is also used in RX packet timestamping;
this may improve adhoc mode on the 11n chipsets. It also will affect the
timestamps seen in radiotap frames.
